“…Sensilla styloconica type 1 observed in this study match the features of sensilla styloconica type 1 in C. remissa (Zheng et al 2014). They are widely distributed on the antennae of moths (Castrejón-Gómez & Carrasco 1999;Wall 1978). Sensilla styloconica type 2 occurring on the antennae of C. chinensis appears to be identical with respect to the structural and location in M. villosus (Merivee et al 1999) and Psylliodes chrysocephala (Bartlet et al 1999).…”

Callosobruchus chinensis (Coleoptera: Bruchidae) is the main pest of mungbean (Vigna radiata) especially during seed storage. To provide background information for chemical ecology studies, we examined the externalmorphology of the antennal, maxillary palp and labial palp sensilla of this insect with scanning electron microscopy. The antennae of adult C. chinensis exhibited sexual dimorphism. The female have serrated antenna and the male have pectinate morphology. Eight sensillum types have been observed on the antennae of both sexes: Böhm bristles, sensilla chaetica, sensilla trichodea, sensilla basiconica, sensilla styloconicum, sensilla coeloconica, sensillum campaniformia, sensilla cavity. There are no differences on the morphology of maxillary palp and labial palp between female and male. Four different types of sensilla are present on the labial and maxillary palps of both sexes of C. chinensis: sensilla chaetica, sensilla twig basiconica, sensilla basiconica, sensilla digitiformia.

“…Th e number of segments per fl agellum did not vary with sex (62.8 ± 1.7 for males and 64.2 ± 1.0 for females; p = 0.8789, Mann-Whitney U-test). Sensilla styloconica, coeloconica, chaetica and trichoidea observed in B. fusca have already been described on the antennae of other noctuids such as Trichoplusia ni (Hübner 1802); Helicoverpa zea Boddie 1850; Spodoptera ornithogalli (Guenée 1852), Spodoptera exigua (Hübner 1808), Pseudaletia unipuncta (Haworth 1809) and Copitarsia consueta (Walker 1857) (Jeff erson et al 1970;Lavoie & McNeil 1987;Castrejon-Gomez et al 1999).…”

“…For both male and female B. fusca, one sensillum styloconicum was visible on the terminal part of each antennal segment as well as on the apical segment showing a double structure, which is frequent in noctuids (Castrejon-Gomez et al 1999). Th ese sensilla were argyrophilic or silver stained from their apical part (fi g. 2), indicating the presence of an apical pore that suggests contact chemoreceptive function (Jeff erson et al 1970).…”

Abstract. The number and distribution of chemosensilla located on different organs of Busseola fusca (Fuller) (Lepidoptera: Noctuidae) males and females are described based on observations using scanning electron microscopy, selective staining with silver nitrate, and gustatory electrophysiological recording. The antennae and the fi fth tarsomere of the prothoracic legs of both sexes bear chemosensilla: uniporous chaetica and multiporous trichoidea sensilla. However, there is a sexual dimorphism in the number and size of sensilla on these organs. The distal part of the ovipositor has uniporous gustatory chemosensilla of the chaetica type. The involvement of these sensilla in oviposition site selection by B. fusca is discussed. Résumé. Dimorphisme sexuel des sensilles chémoréceptrices des antennes, des tarses et de l'ovipositeur du foreur de graminées africain, Busseola fusca (Fuller) (Lepidoptera: Noctuidae).Le nombre et la distribution des sensilles chémoréceptrices présentes sur les différents organes sensoriels des mâles et femelles de Busseola fusca (Fuller) (Lepidoptera: Noctuidae) ont été étudiés sur la base d'observations en microscopie électronique à balayage, par leur réponse à une coloration sélective au nitrate d'argent et à l'électrophysiologie de contact. Les antennes et le cinquième article des tarses des pattes antérieures des deux sexes possèdent des sensilles chémoréceptrices identifi ées respectivement comme de type chétiforme uni-poreux et comme de type trichoïde multi-poreux. Un dimorphisme sexuel est observé par rapport au nombre et à la taille de ces sensilles. La partie distale de l'ovipositeur possède également des sensilles chémoréceptrices gustatives chétiformes. Le rôle de ces structures chémoréceptrices dans la sélection du site de ponte chez B. fusca est discuté.

Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is a serious polyphagous pest of various field and horticultural crops. A complete knowledge on the morphological features of antennal sensory structures is essential for efficient semiochemical-based control methods. The external structure and distribution of antennal sensilla in male and female adults of H. armigera were investigated using scanning electron microscopy. Eight distinct morphological types of sensilla were identified in both sexes: sensilla trichodea, sensilla basiconica, sensilla auricillica, sensilla coeloconica (multiporous), sensilla chaetica (uniporous), sensilla styloconica, sensilla squamiformia, and Böhm sensilla (aporous) in varying numbers and distribution along the length of the antennae. Of these sensilla, the most widespread are sensilla trichodea and sensilla basiconica on the antennae of both sexes. Female antennae have comparatively greater number of sensilla trichodea than male antennae. Among eight types of sensilla, sensilla basiconica, auricillica, styloconica type II, squamiformia, and Böhm sensilla were identified and reported for the first time in H. armigera. Sexual dimorphism in H. armigera was mainly detected as the variations in sensilla shape, numbers, and distribution of each type of sensilla. The sexual difference was observed in the numbers of sensilla coeloconica, chaetica, styloconica, and squamiformia per flagellomere.The possible functions of these sensilla were discussed in view of previously reported lepidopteran insects. The findings provide fundamental information on the morphology and distribution of antennal sensory structures in H. armigera. It would be useful for further detailed studies on physiological and behavioral function of each sensillum type and helpful for formulating related pest control methods.
